Hello everyone, this is my first post here. I’ve listened to the show for a long time, and now that I’m having some car trouble, I’m hoping I can get some help. I’ve had my Volvo 240 for about four years now, and since I bought it, my A/C has never worked. All of the fans and compressors sound like they work, but it only blows hot or, at best, room temperature air. This year it’s been especially hot so I thought I’d take it in and get it fixed, but my mechanic isn’t authorized to work on systems that us r-12 coolant. I can convert it myself, or at the very least drain it, she said, but she can’t get involved with working on r-12. I thought I’d try to do it, but when I open the hood, I have no idea what it is I’m looking at. Can anyone perhaps provide a diagram and some instructions on what to look for and how to drain the system? Thanks.
